Condensate Drain Pump Installation

The float switch and the reservoir make up a condensate pump.

Condensate drain pump installation.

Locate the drain where the condensate will be sent. Riley archer is the product manager for aspen pumps at rectorseal corp. Figure 3 connection of a condensate pump typical method nb manufacturer s detailed instructions should be followed. For the primary condensate drain the installer piped 3 4 pvc into a condensate pump which will discharge into a nearby vanity sink prior to the trap via 3 8 vinyl plastic tubing.

Ensure all pvc joints are cleaned and glued properly so they do not leak. That doesn t necessarily mean the pump is bad. Note any external pipe work should be insulated pipe cut at 45 degrees and a drain leaf guard fitted. So furnace installers mount a condensate pump right on the furnace and route the drain line to a far off sink or floor drain.

Once the condensate reaches a specific level the condensate pump is turned on by the built in float switch. If that condenser pump fails the water overflows the pump and spills onto the floor. Stop the pvc pipe above the furnace for now until the condensate pump is installed. The problem could be just algae buildup in the pump s check valve.

The reservoir is connected to the drain pan where it collects water while your mini split unit cools. Install pvc pipe from the drain back to near the furnace. Anchor the pipe to the ceiling or wall depending on how it is run. Before installing the pump let the air conditioner run a few cycles so that some condensate collects and to remove any oils that are left in the system.

For the secondary drain system he installed a wet switch within the pan below the unit which will turn the unit off upon water detection. Mini split condensate pump selection and installation is critical for providing indoor air comfort and avoiding property damage from evaporator drain pan overflows.
